DETAILED DESCRIPTION OF THE INVENTION

(6) By way of example and not of limitation, the apparatus and system of the present invention generally comprises one or more independent self-contained fueling stations that can be placed in remote locations without an on-site attendant or connections with wired telephone or electrical utility power sources. The station control components are preferably in communication with a central control center through a wireless link that permits remote monitoring and operating of all the station systems and sub systems from the central control center 20.

(7) Turning now to FIG. 1 and FIG. 4, one embodiment of the invention, the dispensing docking and coupling system 10 is schematically shown. The station shown is configured with on board fuel tanks 11 for fuels of all sorts (gasoline, pesticides, water, fertilizers etc. In another embodiment, multiple tanks or multiple tanks with compartments may be used for fuel storage.

(8) The tanks 11 have filling portals. Fuel is transported to the station location by tanker truck and deposited through the filling portals.

(9) The tanks 11 preferably have fuel level sensors 22 that continually monitor the level of the fuel in the tank. These monitoring sensors will also verify the amount of fuel delivered to the station by the fuel delivery truck and deposited in the tank as well as the remaining fuel available. Other fuel sensors continuously monitor secondary spaces around the storage tanks, inside sumps, and the secondary space of double wall piping to detect any breaches of the primary containment. The station can normally run without human intervention from several weeks to several months depending on the size and number of storage tanks.

(10) FIG. 4, another embodiment of the invention, the subsystem of tanks of all sizes that can be fitted to (UAV) of all sizes and has a coupling and docking system designed to couple to the preferred system 15 is schematically shown.

(11) Although only several storage tanks 11 are shown, it will be understood that a plurality of storage tanks can be used. In addition, storage tanks can also be used to store fuels of all sorts. The storage tanks 11 are connected to one or more dispenser docking and coupling systems. In the embodiment shown in FIG. 1 and FIG. 4, the dispenser docking and coupling system 10 are connected with a fuel piping and pumping system 12 to the fuel tank 11.

(12) The dispenser docking and coupling systems 10 can be disabled with a signal from a security system in case of dispenser damage or malfunction or with a loss of electrical power when station sensors indicate damage.

(13) The station control center is an on-board computer 13 with programming and storage that is connected to the station sensors, security system, communications system, dispensing systems, energy production and storage system, and station status monitoring and control systems. In one embodiment, the station control center has a second redundant computer as a backup in case of failure by the primary station control computer.

(14) The station control center on-board computer 13 is preferably connected through the communications link to a central command center at a remote location so that the sensors, a security subsystem 24 with digital cameras and a remote monitoring system, power functions, the station on-board control computer 13 and other operations can be controlled remotely from the central command center. The central command center may exert control over the station control center 13 and station components with a supervisory human attendant or with a command computer that has programming that responds to selected conditions at the station and also monitors and records sensor and status data from the station on-board control computer 13.

(15) The preferred system has a central command center with a central control computer in communication with a station on-board control computer 13 at one or more satellite locations through a wireless communications link. The station on-board control computer 13 has control over the activities of the station and its sub systems. The station on-board control computer 13 and the various subsystems can be controlled remotely by the command center.

(16) The station control center housing 14 may have an optional heating or cooling system to control the environmental conditions of the station on-board computer, sensors, e.g. temperature sensors 26, or other components with the housing to protect them from large variations in temperature. Temperature extremes may cause malfunctions or shorten the lifespan of sensitive electronic components.

(17) In one embodiment, the station on-board control computer automatically generates reports regarding sensor data, fuel dispenser status, fuel level status, electrical system status and other desired statistics or data and sends them through the communications link to the command center for evaluation. Diagnostic tests and computer programming and troubleshooting can also be performed remotely from the central command center. Transmissions of the data to the command center may be dynamic or scheduled. Evaluation of the transmitted station data may be conducted by a remote monitoring attendant or by the programming of a command center computer that can generate an alarm if conditions exceed predefined limits.

(18) The station control center 13 on-board computer can also generate and transmit an alarm to the command center when a malfunction in one of the sub systems, or an act of vandalism or extreme weather conditions and the like are detected. Alarms may identify circumstances that require the attention of a maintenance worker to travel to the station to replace, repair or troubleshoot a component. A remote attendant can also exert remote control over the station in response to an alarm.

(19) The station is preferably powered by a power source 28, e.g. a solar energy source and a battery bank that is part of an energy production and storage subsystem. The preferred primary source of electrical power is a renewable energy source in the form of an array of solar cells. The electrical power that is produced is used primarily to power the pumps and other station energy needs. Excess power from the solar array or other power source is used to charge the batteries of the battery bank. At night or where power consumption exceeds production by the solar array, a generator can be actuated to recharge the battery bank or to provide electricity directly for station pumps and other systems. The generator can be fueled by liquid fuel or gas fuel. The generator may have its own fuel supply or may be connected to any of the on-board fuel tanks 11 so that the generator has access to a large fuel reserve. The generator may also be fueled by propane or other flammable gas kept in storage tanks on the station.

(20) In the embodiment shown in FIG. 1,2,3,4, the supply of electricity for the station is independent of the power grid so that the station is electrically self-sustaining supported by renewable energy, battery storage and fueled auxiliary electricity generation. The renewable energy source provides power to the station and the battery storage supplements any electrical demand in excess of production.

(21) The electrical demand for the docking, coupling, fueling, station status and sensor, communication, security and control systems is provided from three different prioritized sources: solar, battery and auxiliary generator.

(22) Alternatively, if the charge capacity of the battery bank drops and the solar production is low, the electricity can be provided by an electrical utility where power from a utility is available. The external power from the utility is used to charge the battery bank and to supply the station power demand until the battery bank is fully charged or the power from the solar cells becomes available.

(23) From the discussion above it will be appreciated that the invention can be embodied in various ways, including the following:

(24) The preferred system as a motorized vehicle.

(25) The preferred system as shown in FIG. 3, a self-propelled unmanned motorized vehicle that can be operate by remote control with an auto-steering guidance systems 30 through a communications link to the command center or satellite station.
